Application filed January 22, 1916.

To all whom it may concern:

Be it known that I, ARTHUR G. SooLE, a citizen of the United States,residing at the city and county of San Francisco, State of California,have invented a new and useful Improvement in Window-WVeatherproofing,of which the following is a specification.

This invention relates more particularly to means for weather-proofingwindow sashes within the window frame with special reference to theparting beads interposed between the frame and the separate sashes.

In this specification and the annexed drawings, I illustrate theinvention in the form that I consider the best, but it is to beunderstood that I do not limit myself to such form, because the saidinvention may be embodied in other forms; and it is also to beunderstood that in and by the claims following the description I desireto cover the invention in whatever form it may be em bodied.

In the accompanying one sheet of drawings:

Figure 1 is a side elevation in vertical cross-section of thewindowcasing having two sashes slidable therein, weather-proofed in accordancewith this invention.

Fig. 2 is an enlarged detail in horizontal section taken on the lineII-II, illustrating the interlocked divided parting bead and thepressure plate.

Fig. 3 is a similar View illustrating a modification of the partingbead.

Fig. 4 is an enlarged detail in perspective of the pressure plate.

Fig. 5 is an enlarged detail of the pressure plate shown incross-section interposed between the edge of the sash and the stop.

In detail the construction illustrated in the drawings include: a windowframe com prising the sill 1, the stool 2, the lintel 3, the usualinside and outside trims 4 and 5 across the bottom, 6 and-7 across thetop, and 8 and 9 at the sides. The top and bottom portions of the frameare oined by the side jambs 10 on opposite sides and provided withlongitudinal grooves 11 to receive the parting beads. The interior ofthe frame is provided with a stop 12 in the usual manner. The outsidetrim 15 overhangs the side jamb-s and lintel to form a stop for thesashes.

In general construction the upper and lower sashes are conventional,respectively consisting of the glazed. frames having side Specificationof Letters Patent.

stiles 16 and 17 and top and bottom rails 18 and 19 and meeting rails 20and 21. The meeting rails of the sashes have interlocking tongue andgroove portions adapted to exclude the weather at this point.

The invention includes the following adaptations to the above describedconstruction. The parting head is preferably divided laterally as bestdisclosed in Fig. 2, the two strips 22 and 23 are slidable in the slot11 in the side jambs 10 on opposite sides of the window frame. Theparting strip 22 is provided with a longitudinal groove 24 to receivethe projecting tongue 25 on the strip 23; this construction breakscapillary attraction, preventing moisture passing into the groove 11 andalso excludes air drafts at this point. The groove 24 is wider than thetongue 25, which permits the lateral adjustment of the two strips 22 and23 with respect to each other. The strips 22 and 23 are provided withlongitudinal beads or tongues 26 and 27 engaging grooves in the faces oftheir respective continguous sash stiles 16 and 17. This tongue andgroove arrangement excludes weather at this point and aids in guidingthe vertical movement of the overlapping sashes. The lateral division ofthe parting bead permits their respective tongues 26 and 27 to adjustthemselves to the grooves in the sashes. When properly adjusted theparting beads may be nailed within the grooves 11, or they may bepermitted to slide laterally therein to accommodate themselves to anyvariation in the vertical movement of the sashes. The parting beadsextend from the sill to the lintel 6; the meeting rails of the sashesare cut away to clear the parting beads on opposite sides of the sashes.

To maintain the snug fit of the sashes with the parting beads the stiles16 and 17 are provided with longitudinal pressure plates 28 and 29.These plates bear against the inside stops 12 and the outside stops l5respectively. These pressure plates are forced outward by the tension ofthe springs 30 and 31 confined within hole bored into the sash stiles.To prevent the displacement of the pressure plates they are providedwith the lugs 3232 engaging the holes 33-33 bored in the side stiles ofthe sashes.

The beveled weather bead 34 is let into the lintel 3 to engage atransverse groove in the top rail 18 of the upper sash when the sash isin the closed position. in Fig. 1.

This effectively stops the entrance of weather at this point. Themeeting rails 20 and 21 overhang each other as illustrated in Fig. leffectively weatherproofing the joints between the sashes at this point.The bottom rail 19 is provided with a transverse groove to engage thetransverse tongue 35 formed on the sill l effectively weathering thelower rail of the lower sash at this point. The adjacent sides of bothsashes are effectively weather-stripped by the tongue and groovedparting beads 22 and 23 engaging the window frame on both sides. All ofthese various means recited cooperate to effectively weatherproof thesashes within the window frame while in the closed position.

The form of parting bead illustrated in Fig. 2 is adaptable to thereconstruction of old windows, by substituting a parting beadconstructed in accordance with this invention for the existing partingbead made in one piece as usual. This is accomplished by plowing thegroove in the sash-stiles to receive the tongues 26 and 27, and boringthe opposite sides of the sash to receive the pressure plates 28 and 29.A modification of this strip is illustrated in Fig. 3 by means of whichmore material is possible in the parting bead. The extra thickness ofthe bead is provided for by rabbeting the edges of the sash to receiveit, the thickness of the parting bead being reduced to enter theconventional width of groove 11 in the jambs 10 of the window casing.Other modifications in the structure may be made to suit specialconditions without departing from the spirit of this invention.

Having thus described this invention, I claim:

1. In a window, a frame, sashes slidably mounted in said frame, partingbeads freely mounted in the sides of said frame between said sashes,each bead being divided longitudinally into two parts, engaging means tohold said parts together but to allow said parts to move laterally withrelation to each other within the sides of the frame, and engaging meansbetween each bead part and a sash permitting movement of the sasheslongitudinally of said bead parts-and causing said bead parts to movelaterally with the sash.

2. In a window, a frame, sashes slidably mounted in said frame, partingbeads freely mounted in the sides of said frame between said sashes,each head being divided longitudinally into two parts, a longitudinallyextending tongue and groove engagement between the parts of each bead tohold said parts together but to allow a slight relative transversemovement of said parts, and a longitudinally extending tongue and grooveengagement between each bead part and a sash permitting movement of saidsashes longitudinally of said head parts and causing said parts to movelaterally with said sash.

3. In a window, a frame, sashes slidably mounted in said frame, partingbeads freely mounted in the sides of-said frame between said sashes,each bead being divided longitudinally into two parts permittingrelative transverse movement of said parts in the sides of said frame,and engaging means between each bead and a sash permitting movement ofthis sash longitudinally of said bead parts and causing lateral movementof the bead parts with the sash.

4.. In a window, a frame, sashes slidably mounted in said frame, partingbeads freely mounted in the sides of said frame between said sashes,each bead being divided longitudinally into two parts permittingrelative transverse movement of said parts in the sides of the frame,and a longitudinally eX- tending tongue and groove engagement betweeneach bead part and a sash permittingmovement of said sasheslongitudinally of said bead parts and causing said parts to movelaterally with said sash.

5. In a window, a frame, sashes slidably mounted in said frame, partingbeads freely mounted in the sides of said frame between said sashes,engaging means between said beads and sashes permitting movement of thesash longitudinally of the beads and causing the beads to move.transverselyv with the sashes.

6. In a window frame, sashes slidably mounted in said frame, partingbeads freely mounted in the sides ofsa-id frame between said sashesengaging means between said beads and sashes permitting longitudinalmovement of said sashes with relation to said beads and causing thebeads to move transversely with the sashes, said beads being soconstructed and arranged as to enable eachsash to move laterallyindependent of the other sash.

In testimony whereof, I have hereunto set my hand at San Francisco,California, this 15th day of January, 1916.
